What is epic seven catalyst?

Epic Seven Catalysts are items that are used to enhance the abilities of units in the game. They are divided into two main categories: Equipment and Enhancement.

Equipment Catalysts are items that can be used to craft equipment. Each equipment item requires a specific set of catalysts for crafting. For example, the 4-2 Gold Challenge drops Cerberus teeth and Bright Crystal Anemoculus. These catalysts can be combined with other items to craft a variety of equipment.

Enhancement Catalysts are items that can be used to enhance units. To enhance a unit, a player must first select the unit they wish to enhance, then select the desired catalyst. The catalyst increases the unit's level, star rank, or skill levels, depending on the type of catalyst selected.

Catalysts can be found in a variety of game modes and locations. Some catalysts are obtainable from completing specific stages in the game, while others are available through summoning, crafting, or other means. Some catalysts are rare and difficult to obtain, making them highly sought after by players who wish to power up their units.
